Setting up the factory was a challenge, too. Citing difficulties finding the right machinery in the U.S., Shapiro ordered the machines from overseas. This turned into a lengthy process. Considering the instructions weren't in English, it took the team awhile to figure out how to use the equipment and train the workers.

Almost half of State Optical Co.'s workers previously worked in the auto industry.

Finding skilled labor was the next hurdle. About half of the the firm's workers were previously employed in the auto or jewelry industries and underwent extensive training to learn how to make eyewear.

Each eyeglass frame, made from a sheet of acetate, requires 75 steps from start to finish. About half of the process is done by hand.

The startup, which pays an average salary of up to $15 an hour, gives full benefits, such as healthcare and paid vacation, to workers.

Shapiro hopes the move will inspire other entrepreneurs to move eyewear production to the U.S..

"[State Optical] started with the belief that we could manufacture this product in the country. and put Americans to work," he said. "For most who buy our eyeframes, it will be the first time wearing U.S.-made eyewear."
